This tester is intended to quickly check whether a transistor is functional or not and possibly also select two or more transistors with (approximately) equal gains. This is about the simplest ...

Why might you need semiconductor system-level test (SLT)? As Karthik Ranganathan, director for semiconductor solutions at Astronics Test Systems, points out, if you test a 22-nm, ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...
